Specification of Letters Patent. Application filed November 30, 1906. Serial No. 345,588.

Patented April 23, 1907.

To @ZZ whom, it 717/652/ concern:

Be it known thatA I, PETER BRoADBooKs, of Batavia, in the State of New York, have invented certain new and useful Improvements in Vises; and I hereby declare thatv right or left while .the base-plate can beturned so as to swing the jaws horizontally right or left; this combination of a vertical and horizontal adjustment enabling the object gri ped by the jaws to be sition esired by the operator.

The vise can be locked in any desired position by simply manipulating one hand-wheel or nut beneath the base-plate and by loosening this nut the 4jaws can be rocked on the base and the base turned in any desired position, and by tightening the nut the parts are rigidly locked in any desired position. This nut is located underneath the work-bench, hence is readily accessible and obviates the necessity of removing the work from the vise.

The vise is also provided with removable Tand changeable pipe or rod-gri ping clamps which enables it to be used for Folding round work as well as straight or angular work.

In the accompanying drawings I have illustrated the vise and will now explain the n same in detail by reference to such drawings :40" and refer to the lsection on line 3-3,

claims as part of the description for summaries of the parts for which protection is desired.

In said drawings-Figure l is a perspective view of the complete vise in upright position. Fig. 2 is an enlarged perspective view showing the vise swung to the right. Fig. 3 is a Fig. 1, showing the jaws swung left and right in dotted lines. Fig. 4 is j a longitudinal section on lines 4 4, Fig. 3. Fig. 5 is an enlarged section on hne 5-5, Fig. 4. Fig. 6 is a section on line 6-6, Fig. 4. Fig. 7 is a perspective view of the pipe-gripping jaws detached.

Theb circular tral aperture 1a held in any poing and pivot bolt 2. It is also formed on its upper surface with a diametrical disposed projection lb which is concaved on its inner surface as at le, to fit the lower cylindrical portion 3a, of the rocking-j aw 3. The lower portion 3a of this rocking jaw is shown in part as cylindric to fit in the concave bearing of the rocker-plat@ and long enough to revent longitudinal oscillation on the roc erplate but can turn laterally on said plate and support the jaw whether it be in sition or turned to either side as Fig. l3. From this portion 3a nut portion 3b on the the jaw proper.

rises a vertical upper end of which lis Through the parts 3%, 3l?,

vertical oindicate mi,

extends a longitudinal slot 3 in which is :lit-

ted a sliding jaw 4.

The cylindric portion 3a of the rocking aw is provided in its under side and below slot 3c bar 5, carrying the adjustable with a transverse slot 3d.which triangular in cross section as shown'in Fig. 4,'.and being wider in its inner side than at bottom and its walls ta ering from the upper or inner mouth of te slot to the outer orv bottom mouth of the slot. And the head of the bolt 2, extends into the slot 3d and prevents longitudinal movement of the roc jaw on the rocker-plate. The head 2aL of this bolt 2 viewed from the front. is the same width as the shank of the bolf 4but viewed from the side it is triangular, see Fig. 4, and has a V- shape,*the bevel sides of the heads conforming to the bevel wallg of the slot 3d and bein adapted to frictionally clamp the Walls of said slot when'the nut 2b on the lower end of the boltis tightened. This bolt can be readily inserted into the slot 3i by turning its head lengthwise of the slot and after insertion into the slot 3d, the head is turned transversely of the slot and then the head will engage the walls ofthe slot as indicated inFig. f

4, and will retain the rocking aw in position upon the rocker-plate. By loosening the hnd nut 2b, the rocking jawr can be swung righil or left as indicated in Fig. 3, in avertical plane and the rocking jaw and rocker- IOO plate can be turned right or left in a horizontal plane as indicated in Figs. l and 2, and when adjusted to the desired position by simply tightening nut 2b the rocker jaw and rocker-plate will be held rigidly until the nut l 'LB'again loosened. ase or rocker-plate l is approximately j in plan and is provided with a cenfor the passage of the fasten-i may beadjusted on said bar The adjustable jaw 4 is slidably mounted upon the outer end of the sliding bar 5, and byjlneans of the IIO screw 4a and end piece 4b as usual, and it may be' desired to positively lock to theside bar by means of tap-bolt 4. The sliding bar 5 may be made of cast-iron reenforced-with mould and incorporated in the bar during the casting operation. These steel bars extend the entire length of the sliding bar and give great strength thereto.

ro Preferably the bottom of the opening or longitudinal slot 3, in the rocking jaw through which the bar passes, is made with an angle, as indicated in Fig. 3, the apex of the angle V4e forming a fulcrum or bitingpoint for the sliding jaw,*the top of the opening being 4slightly tapered as at 4f soas to permit the bar when lifted at its outer end to ,be free from the fulcrum and therefore readily adjusted longitudinally, but when zo lowered upon the fulcrum the latter will bite the bottom-of the sliding bar and lock it and the movable jaw relatively to the rocking jaw. To insure thebiting action `of the fulcrum, I preferably make this sliding bar with z 5 angular grooves in its sides, as indicated in Fig. 3,.and tap through the walls of the rocking aw bolts 6, on opposite sides of the aw,

see Fig.- 3, vthe inner ends of which are adapt-l ed to engage the opposite bevel walls of the 3o lower ends of the grooves in the sliding bar and when the outer end of the sliding bar is lowered, and thus insure its being heldby the fulcrum.

j In addition tov side bolt 6, a third side bolt 3 5 68L may -be tapped through the rear upper surface of the jaw in positlon to have its lower ends engage with'the top ofthe bar 5, in rear of the fulcrum and aHord an additional bearingfor said bar. This third bolt 6a being particularly useful on very heavy vises as it gives the bar three bearing points against bolts 6, 6a, on its upper side.

To' assemble the vise, the rocker-plate 1 is placed upon thev bench or support to which the vise is to be attached over a suitable opening in the bench. lower end of thebolt. inserted in the slot 3d in the lower portion of the rocking jaw and givena quarter turn so that its head will engage the walls of the slot, as indicated in Fig. 4, then the bolt is inserted through' the rocker-plate and the nut 2b screwed on the lower end thereof so as to hold the rocking jaw `upon the rocker-plate. The bar 5, to which the movable jawhas been previously connected, is then inserted through the slot 3, in the rockin@ jaw and the vise is read for operation. t will be seenthat when the handle-nut 2b is loosened the, wise may be turned as a whole right and left'onthe rocker-plate and the rocking jaw can also be swung to right or left on the rocking plate, thus assembling the vise quickly in any desired position. By simply lifting the adjustable jaw so as to rock the bar 5 on its steel rods 5a, which may be arranged in thev for the passage of the The bolt 2, is then fulcrurn 4e and clear its upper surface from the bolts 6, 6a, the movable jaw can be quickly moved toward or from the rocking jaw, so as to get quick action and bring it up to its work, .then when it is released the slid- 7o ing bar 5 is locked by fulcrum 4e and contacts with points of bolts 6, 6a. The movable jaw can then be adjusted by the operating screw 4a so as to more tightly clamp the work.

In order to adapt thevise for holding round objects such as pipes or rods, I provide the jaws 3 and 4, with removable clamping plates 7, shown more` clearly in Fi s. 5 and 7 These clamping plates are ma e of sections riveted or screwed together as at 7a and properly separated by interposed blanks 7b, and the plates attached to one jaw alternate wi th those attached to the other jaw, as indicated in Figs. 5 and 7, so that they do not come directly opposite each other but will telescope and consequently thev inner V- shaped clamping edges of these plates can engage and securely hold various sizesA of pipes. By making these gripping plates in sections, I avoid the necessity of re-sharpening the entire set or replacing the entire set in case of damage to any one of them. These pipe die-stocks maybe detachably attached to thejaws Sand 4, which jaws are provided with recesses 4m and 3m, below their straight 95 work-clamping portions, into Whichrecessesy or sockets the base of a nest of die-stocks can be inserted and secured by bolts or rods 3, 4, as indicated in the drawings. This facilitates the removal of the die-stocks for repairs orl when it is not desired to use the same. These ipe die-stocks are each made up'of several p ates 7, which are thin and can be punched out Yto gage so that if one plate needs sharpening or to be replaced by another, this can be done at less expense than roo with thick plates of the ordinary pipe vises.

The plates in my die-stocks being close together will hold up more firmly and will not bend or injure the pipe as will vises wherein the stocksiare thick and the spaces .consequently large.

Bymy improved vise the work need not be disturbed while shifting the vise to different angles or positions. justed practically instantaneously to the work. The adjustments either rocking or revolving the vise arevery simple and yet very positive the vise can be rigidly fixed at any angle or position and my vise is specially 1 z o desirable for machinists use and as a combination pipe vise.
